Abstract

The invention relates to a disk brake for vehicles, in particular to a pneumatically actuated disk brake for utility vehicles, comprising a brake saddle and a clamping device for clamping the brake. Said clamping device has a first component in the form of a rotary lever which is displaceably guided on a second element, such as a brake saddle, by means of a needle bearing (1). According to the invention, the disk brake is characterized in that the inner ring (3) is embodied as a bearing cage made of plastic, said cage enclosing on its outside an evenly configured ring of sheet metal serving as exterior bearing.

Description

Has the disk type braker that the automobile of hold down gag of band needle bearing is used
Technical field
The present invention relates to a kind of by claim 1 disk type braker that is used for automobile as described in the preamble, especially for the disk type braker of the air-operated control of commercial car.
Background technique
According to the claimant's of present patent application product name SB6 and SB7 and SN6 and SN7, disk type braker of the same type is known with various forms of implementation.The present invention is particularly suitable for using on this break, but also be suitable on the principle using at the disk type braker of other types, the torsion bar of the particularly eccentric support of wherein mobilizable first brake member is realized by the needle bearing of a circular arc in the supporting of another brake member.Call outer ring and inner ring rather than brake member at this ring that does not seal, their arc ground on the part of circle extends.
In order to support brake member mutually relatively versatilely, needle bearing or roller bearing with outer ring, inner ring and one group of needle roller prove effective.The requirement of optimization is proposed for the relative higher cost expense of making this needle bearing especially.
Summary of the invention
The objective of the invention is to, address the above problem.
The present invention achieves the above object by the theme of claim 1.
To this, the retainer that inner ring is designed to be made of plastics, its U-shaped ground surrounds " flat " thin slice ring as external support.Because the outer ring is made by tinsel, it can be with simple method manufacturing in unique BENDING PROCESS except functional element such as lug boss etc., and because the inner ring that is made of plastics is born the effect of the retainer wall of side direction, this inner ring can be with low cost mode for example as the moulding manufacturing, so function compared with prior art also keep identical at least or even improved situation under reduce the manufacture cost of needle bearing and reduce the manufacture cost of disk type braker thus.Therewith relatively, make the arc plate of the retainer wall with two side direction by the prior art outer ring, described retainer wall only can be installed on the stone tinsel that is adopted with manufacture process costliness by means of cost is high.Opposite with above-mentioned expectation, the function on different the is retainer border of side direction is transferred on the interior ring that is made of plastics.
Favourable structure draws from dependent claims.
Description of drawings
Followingly illustrate in greater detail the present invention by means of embodiment with reference to accompanying drawing.In the accompanying drawing:
Fig. 1 a-e is by the different view of needle bearing of the present invention;
The perspective view and the partial view of the inner ring of the needle bearing of Fig. 2 a-b Fig. 1;
The perspective view of the outer ring of the needle bearing of Fig. 3 Fig. 1.
Embodiment
Fig. 1 illustrates one and is used for the disk type braker that do not illustrate at this, it is particularly useful for torsion bar is bearing on the brake calipers of disk type braker for example, as it for example according to product name SN6 or SN7 or for example known by DE4204307A (referring to roller bearing there) or DE19731696A with similar structural type.Structure for the disk type braker that does not have at this further to discuss quotes in full described document.
Have the outer ring 2 of circular arc and the inner ring 3 of attaching troops to a unit at the needle roller shown in Fig. 1 or roller bearing 1, one group of needle roller 4 is set between them in this wise, make that outer ring 2 can be with respect to inner ring 3 rolling bearing versatilely.
Inner ring 3 is made of plastics and is provided with two perpendicular to the outside retainer walls 5 (also referring to Fig. 2) of directed side direction of inner ring, described retainer wall 5 towards the outer ring 2 direction extend and the described outer ring of U-shaped ground encirclement laterally.
Also referring to Fig. 3, outer ring 2 is made by flat tinsel, and this tinsel is curved cylindrical segment or curved circular arc.It has the recess 6,7 of two side direction in its both sides, the retainer wall 5 of inner ring is embedded in the described recess, wherein recess 6,7 has such length, make inner ring in the recess of outer ring 2 limited versatilely the guiding, thereby recess 6,7 is born the function of the backstop of restraint on the one hand in simple mode, outer ring 2 is guided well and remained in the mounting point on inner ring 3 on the other hand.
Fixing device such as lug boss 8 and/or hole 9 with inner ring 3 and/or outer ring 2 be fixed on corresponding that attach troops to a unit, can be mutually relatively versatilely on the brake calipers and torsion bar (not shown) of the member of supporting such as disk type braker.
The inner ring 3 that is made of plastics has the chamber 10 that is used to hold each two needle roller 4 of a plurality of spaces shape.On the contrary, the outer ring of being made by sheet material 2 is made by tinsel, this tinsel can only be made in simple mode in unique BENDING PROCESS except lug boss 9, thereby but compares explicit costs with known needle bearing by needle bearing of the present invention and make cheaply and do not influence any function.
